When should you replace your car's brake pads?

1. Squealing and screeching brakes

The first sign that any driver will notice is a screeching sound when braking. This sound is caused by a small metal part on the brake pads that serves as a warning. When you hear this unusual sound every time you brake, it is time to see a technician to check the brakes.

If the brakes are wet, such as after riding in the rain, the brake pads will often become dirty and you will hear a similar sound when you brake. If the sound then disappears after a few times of braking, it is a sign that the brake pads are rusted but do not need to be replaced.

2. The sound of metal grinding against each other

If you hear a sound like metal grinding or a growling sound, it could be a sign that not only are the brake pads worn, but the brake discs and calipers are rubbing against each other. Friction between two metal parts causes a lot of damage to the braking system, so you should take your car to a service center as soon as you notice the above sounds.

3. Brake pads are 3mm thinner

You can visually check your brake pads to see when they need to be replaced. Look through the spokes on your tire and you will see that the brake pads are pressed against the brake disc. If the brake pads are thinner than 3 millimeters, you should consider having them checked, especially if it has been a while since you had your car checked.

4. Warning light is on

Some vehicles have a warning light on the dashboard that tells you when your brake pads need to be replaced. Consult your owner’s manual to see if your vehicle is equipped with this warning system. Note that once the warning light comes on, you will need to replace your brake pads as well as the brake pad sensor.

- What is brake pad?

Brake pads are located between the brake shoe (the part that tightens and reduces wheel rotation) and the brake drum. If the brake pads do not function properly, other vehicle components such as the brake disc, brake shoes, brake calipers will gradually wear out. Proper maintenance of brake pads helps avoid expensive repairs later on and also limits the situation of losing control.

- How long can brake pads be used?

Brake pads work well for a distance of 48,000 - 56,000 km. However, the condition of the brake pads will vary depending on the type of vehicle and driving style... If you often drive in the city - where traffic density is dense, or the car owner has a habit of accelerating and braking suddenly - needing to brake and release the brake frequently, the brake pads will wear out faster.
